Ecobee SmartThermostat with Voice Control (2019) vs Honeywell Home T9 Wi-Fi Smart Thermostat (2019)

Analysis:

The Ecobee SmartThermostat with Voice Control EB-STATE5-01 (2019) is one of the very best Smart Thermostats that one can get for around $230. The Honeywell Home T9 Wi-Fi Smart Thermostat RCHT9510WFW2001/W (2019), however, while a very good choice at its $150 price point, falls just short of being remarkable.

The Ecobee SmartThermostat with Voice Control EB-STATE5-01 (2019) was loved by reviewers from numerous highly trusted sources that perform in-depth objective testing, including CNET, Wirecutter (NYTimes), Tom's Guide, TechGearLab, and PCmag. It did great in their roundups - it was dubbed "Top Pick" by CNET, "Runner Up" by Wirecutter (NYTimes), and "The best smart thermostat with Alexa" by Tom's Guide. That's high praise coming from sources of such caliber.

As for our analysis of the Honeywell Home T9 Wi-Fi Smart Thermostat RCHT9510WFW2001/W (2019) - it's considered to be a great product by two reliable sources that do their own hands-on testing - it earned the "Best remote sensor" award from CNET and "Best for Multiple Rooms" from PCmag, which is no small feat.

We also took a look at which sources they managed to impress the most. The Ecobee SmartThermostat with Voice Control EB-STATE5-01 (2019) was liked best by TechHive, which gave it a score of 9, while the Honeywell Home T9 Wi-Fi Smart Thermostat RCHT9510WFW2001/W (2019) got its highest, 8, score from TechHive.

Lastly, we averaged out all of the reviews scores that we could find on these two products and compared them to other Smart Thermostats on the market. We learned that both of them performed far better than most of their competitors - the overall review average earned by Smart Thermostats being 7.2 out of 10, whereas the Ecobee SmartThermostat with Voice Control EB-STATE5-01 (2019) and Honeywell Home T9 Wi-Fi Smart Thermostat RCHT9510WFW2001/W (2019) managed averages of 8.3 and 7.3 points, respectively.

Due to the difference in their prices, however, it's important to keep in mind that a direct Ecobee SmartThermostat with Voice Control EB-STATE5-01 (2019) vs. Honeywell Home T9 Wi-Fi Smart Thermostat RCHT9510WFW2001/W (2019) comparison might not be entirely fair - some sources don't take value for money into account when assigning their scores and therefore have a tendency to rate more premium products better.
